Umbral crítico de administración en pacientes con trauma severo y reanimación endovascular: ¿Un concepto útil? / Critical Administration Threshold in severe trauma patients and endovascular resuscitation: A useful concept?

Introducción. Se describe la utilidad del umbral crítico de administración (CAT por su denominación en inglés) como herramienta para la reanimación hemostática en pacientes con trauma severo y oclusión endovascular aórtica. Métodos. Revisión retrospectiva de pacientes adultos con hemorragia por trauma, con o sin oclusión endovascular aórtica (REBOA), atendidos entre enero de 2015 y junio de 2020, en un centro de trauma nivel I en Cali, Colombia. Se registraron variables demográficas, severidad del trauma, estado clínico, requerimiento transfusional, tiempo hasta CAT+ y CAT alcanzado (1, 2 ó 3). Resultados. Se incluyeron 93 pacientes, se utilizó REBOA en 36 y manejo tradicional en 57. El grupo REBOA presentó mayor volumen de sangrado (mediana de 3000 ml, RIC: 1950-3625 ml) frente al grupo control (mediana de1500 ml, RIC: 700-2975ml) (p<0,001) y mayor cantidad de glóbulos rojos transfundidos en las primeras 6 horas (mediana de 5, RIC:4-9); p=0,015 y en las primeras 24 horas (mediana de 6, RIC: 4-11); p=0,005. No hubo diferencias estadísticamente significativas en número de pacientes CAT+ entre grupos o tiempo hasta alcanzarlo. Sin embargo, el estado CAT+ durante los primeros 30 minutos de la cirugía fue mayor en grupo REBOA (24/36, 66,7 %) frente al grupo control (17/57, 29,8 %; p=0,001), teniendo este mayor tasa de mortalidad intrahospitalaria frente a los pacientes CAT-. Conclusión. El umbral crítico de administración es una herramienta útil en la reanimación hemostática de pacientes con trauma y REBOA, que podría predecir mortalidad precoz.

Introduction. The objective is to describe the utility of the Critical Administration Threshold (CAT) as a tool in hemostatic resuscitation in patients with severe trauma and REBOA. Methods. Retrospective review between January 2015 and June 2020 of adult patients with hemorrhage secondary to trauma with or without REBOA in a level I trauma center in Cali, Colombia. Demographic variables, trauma severity, clinical status, transfusion needs, time to CAT+ and number of CAT achieved (1, 2 or 3) were recorded. Results. Ninety-three patients were included, in which REBOA was used in 36 and traditional management in 57. The REBOA group had a higher bleeding volume (3000 ml), IQR: 1950-3625 ml vs the control group (1500 ml, IQR: 700-2975 ml) (p<0.001) and a higher rate of PRBC units transfused in the first 6 hours (median 5, IQR: 4-9); p=0.015 and in the first 24 hours (median 6, IQR: 4-11); p=0.005. There were no statistically significant differences in the number of CAT+ patients between groups or time to CAT+. However, CAT+ status during the first 30 minutes of surgery was higher in the REBOA Group (24/36, 66.7%) vs. the control group (17/57, 29.8%; p=0.001), having this group a higher in-hospital mortality rate vs. CAT- patients. Conclusion. CAT is a useful tool in the hemostatic resuscitation of patients with trauma and REBOA that could predict early mortality.

Mechanism of the effect of Xuebijing injection on neurological function and survival of rats after cardiac arrest/cardiopulmonary resuscitation / 中国药房

OBJECTIVE To explore the potential mechanism of the effect of Xuebijing injection （XBJ） on neurological function and survival of rats after cardiac arrest （CA）/cardiopulmonary resuscitation （CPR） based on the S-nitrosoglutathione reductase （GSNOR）/S-nitrosoglutathione （GSNO） pathway. METHODS The CA/CPR rat model was established by ventricular fibrillation. Using a sham operation group as control， high-throughput sequencing was employed to analyze and mine the differentially expressed genes （DEGs）. Enzyme-linked immunosorbent assay was used to determine the contents of GSNOR and GSNO in the hippocampus； the active components of XBJ were screened and subjected to molecular docking analysis with GSNOR. The rats successfully modeled using the same method were divided into model group （n＝30）， inhibitor （GSNOR inhibitor） group （n＝30）， XBJ group （n＝30） and XBJ+inhibitor group （n＝30）， and a sham operation group （n＝30） was set up. Neurological function was evaluated and survival status was recorded at 3 hours， 24 hours and 3 days after the first 89） drug intervention. The contents of GSNOR and GSNO in the hippocampus of rats were determined in each group at the 0191） above time points， and the relationship of the contents of GSNOR and GSNO with modified neurologic severity scale （mNSS） score was analyzed. RESULTS GSNOR coding gene was differentially expressed between the model group and the sham operation group. Compared with the sham operation group， GSNOR content increased significantly in the hippocampus of rats in model group， while GSNO content decreased significantly （P＜0.05）. The active components of XBJ， such as 4- methylenemiltirone and salviolone， could be bound to GSNOR protein， with the binding energy lower than －6 kcal/mol， mainly connected by hydrogen bonds. Animal experiments revealed that mNSS score and GSNOR levels in the hippocampus of rats in the model group were significantly higher than those in the sham operation group （P＜0.05）， while GSNO levels and survival rate were significantly lower than those in the sham operation group （P＜0.05）. The above indexes of rats were improved significantly in administration groups， the mNSS score in the XBJ group was significantly lower than that in the inhibitor group， the content changes of GSNOR and GSNO in the inhibitor group were more obvious than those in the XBJ group， and the various indicators in the XBJ+inhibitor group were significantly better than the XBJ group and the inhibitor group （P＜0.05）. GSNOR content was positively correlated with the mNSS score， and GSNO content was negatively correlated with the mNSS score （P＜0.05）. CONCLUSIONS XBJ can improve the neurological function of rats and enhance their survival rates after CA/CPR， the mechanism of which may be associated with the down-regulation of GSNOR and the up-regulation of GSNO.

Foi adotado nível de significância estatística 5%. Resultados Foram incluídos 69 enfermeiros atuantes em unidades críticas e não críticas de atendimento ao adulto. A percepção de esforço e a frequência cardíaca foi menor no grupo intervenção (p<0,001), influenciadas pelo dispositivo de feedback, sem diferença significativa quanto às unidades de atuação. Conclusão A escala de Borg mostrou-se adequada para os objetivos propostos. O dispositivo de feedback contribuiu no menor esforço e redução da frequência cardíaca durante as manobras de reanimação. O baixo custo e a facilidade de aplicação favorecem o uso em treinamentos e atendimentos em tempo real para avaliar o desempenho durante a reanimação, utilizando dispositivo de feedback por reduzir os esforços e a percepção do cansaço. Também permite a reflexão sobre os fatores intervenientes e recursos que podem influenciar na qualidade da assistência e nas chances de sobrevivência.

Abstract Background A cardiopulmonary arrest is a critical event whose survival rate is related to the quality of resuscitation maneuvers combined with the use of technology. It is important to understand the perception of fatigue during this procedure, aiming to improve the effectiveness of compressions to increase the chances of survival. Objectives To apply the Borg rating of perceived exertion scale (Borg scale) to analyze the exertion perceived by nurses during cardiopulmonary resuscitation maneuvers using a feedback device. Methods Experimental study with a randomized distribution of nurses in a teaching hospital. Perceived exertion during simulated cardiopulmonary resuscitation with/without a feedback device was assessed using the Borg scale. The statistical significance level of 5% was adopted. Results 69 nurses working in critical and non-critical adult care units were included. Perceived exertion and heart rate were lower in the intervention group (p<0.001), influenced by the feedback device, with no significant difference between critical and non-critical units. Conclusions The Borg scale proved to be adequate for the proposed objectives. The feedback device contributed to lower exertion and heart rate reduction during resuscitation maneuvers. The low cost and ease of application favor its use during training and real-time resuscitation attempts to assess performance using a feedback device to reduce exertion and perception of fatigue. It allows reflection on the intervening factors and resources that can influence the quality of resuscitation attempts and the chances of survival.

Effectiveness of Self-directed Virtual Learning on Retention of Cardiopulmonary Resuscitation Knowledge and Skills among Hospital Nurses in North-western Nigeria: Protocol Paper

@#Introduction: The instructor-led CPR training method has been used for over 4 decades. However, nurses’ knowledge and skills are still low. Instructor-led CPR training is an extremely capital-intensive programme that requires more time, workforce, and space, thus serving as an impediment to effective learning among the prospective nurses’ trainees. Self-directed training method is suggested to improve the knowledge and skills of CPR among healthcare practitioners due to the low cost and flexibility. This study aims to evaluate the effectiveness of self-directed method in improving nurses’ knowledge and skill retention from baseline to post-test, one, three-, and six months. Method: A two-arm double-blinded randomised controlled trial will be conducted in two referral hospitals. The control group training consists of a one-day session taught by AHA-certified instructors, whereas the intervention group training entails participants learning on computers in a simulation lab for seven days. A generalised estimated equation model will be used for statistical analysis. Discussion: Through the self-directed training method, participants will have significantly better knowledge and skills of CPR compared to the conversational training method across the time points. Self-directed training method is a simple, cost-effective and flexible method, which can facilitate the training of more nurses in the acquisition and retention of knowledge and skills, especially for those who prefer to learn at their own pace.

Reanimación cardiopulmonar y cerebral durante el embarazo. Revisión narrativa / Cardiopulmonary and brain resuscitation during pregnancy. Narrative review

Resumen ANTECEDENTES: La reanimación cardiopulmonar representa el 1 a 2% de los ingresos a las unidades de cuidados intensivos. En 2018, 17.4 por cada 1000 pacientes embarazadas de Estados Unidos requirieron reanimación cardiopulmonar e ingreso a unidades de cuidados intensivos, con mortalidad del 52% posterior al primer día de puerperio. OBJETIVO: Aportar conceptos indispensables de reanimación cardiopulmonar, causas de paro cardiaco materno y difundir algoritmos de atención y respuesta luego de la activación de un código para probable cesárea de urgencia en los cuatro minutos posteriores al paro cardiorrespiratorio, en casos sin retorno a la circulación espontánea. Esto con la finalidad de aumentar la calidad de atención de salud y disminuir los índices de mortalidad materna. METODOLOGÍA: Primera etapa: búsqueda en PubMed de artículos con antigüedad no mayor a cinco años, publicados en inglés o español, Guías de Práctica Clínica de Perinatología Clínica, revisiones sistemáticas y metanálisis. Segunda etapa: algoritmo de búsqueda ("cardiopulmonary resuscitation "[MeSH-Terms] AND "pregnancy" [MeSH-Terms]) AND ((y_5[Filter]) AND (systemati creview[Filter]) AND (english [Filter]) OR spanish [Filter])). RESULTADOS: Se reunieron 35 artículos o páginas web de los que se seleccionaron 19, incluidos 3 libros de texto relacionados con el tema y 3 páginas web gubernamentales. Además, se analizaron otros artículos para complementar el conocimiento del tema. CONCLUSIONES: El reconocimiento del colapso materno y la oportuna respuesta del personal de salud permitirán una reanimación cardiopulmonar de alta calidad; por esto debe fomentarse la capacitación al personal de salud.

Abstract BACKGROUND: Cardiopulmonary resuscitation accounts for 1% to 2% of intensive care unit admissions. In 2018, 17.4 per 1000 US pregnant patients requiring cardiopulmonary resuscitation were admitted to intensive care units, with mortality of 52% after the first postpartum day. OBJECTIVE: To provide essential concepts of cardiopulmonary resuscitation, causes of maternal cardiac arrest and to disseminate algorithms of care and response after activation of a code for probable emergency cesarean section within four minutes after cardiorespiratory arrest, in case of failure to return to spontaneous circulation. The aim is to increase the quality of health care and reduce maternal mortality rates. METHODOLOGY: First stage: search in PubMed of articles not older than five years, published in English or Spanish, Clinical Practice Guidelines of Clinical Perinatology, systematic reviews, and meta-analyses. Second stage: search algorithm ("cardiopulmonary resuscitation "[MeSH-Terms] AND "pregnancy" [MeSH-Terms]) AND ((y_5[Filter]) AND (systematic creview[Filter]) AND (english [Filter]) OR spanish [Filter])). RESULTS: Thirty-five articles or web pages were collected from which 19 were selected, including 3 textbooks related to the topic and 3 governmental web pages. In addition, other articles were analyzed to complement knowledge of the topic. CONCLUSIONS: Recognition of maternal collapse and timely response by health care personnel will enable high-quality cardiopulmonary resuscitation; therefore, training of health care personnel should be encouraged.

Reanimación cardiopulmocerebral en la carrera Medicina: diferencias entre los planes de estudios D y E / Cardiopulmonary-cerebral resuscitation in the Medicine career: differences between study plans D and E

Fundamento: la reanimación cardiopulmocerebral básica está presente como curso propio en los planes de estudios "D" y "E" de la carrera de Medicina; aunque en ambos la organización del proceso tiene sus particularidades. Objetivo: precisar las diferencias en cuanto a estructura, proceso docente y resultados académicos en la enseñanza de la reanimación cardiopulmocerebral básica, entre los planes de estudios "D" y "E" de la carrera de Medicina. Métodos: se realizó un estudio descriptivo, prospectivo, transversal, en la Universidad de Ciencias Médicas de Cienfuegos en los años 2017 y 2019. Se utilizaron métodos teóricos y empíricos. Para comparar resultados se utilizó el universo estudiantil en ambos años, para evaluar satisfacción y calidad una muestra aleatoria simple. Se utilizaron técnicas de estadística descriptiva. Para ambos cursos se utilizó similar escenario y claustro de profesores. Resultados: las diferencias entre ambos planes derivan de los componentes no personales del proceso docente; el plan "D" tiene 20 horas y el "E" 40, con lo cual se amplían sus contenidos. Todos los temas y objetivos del plan "D" estuvieron incluidos en el "E". Hubo similitud en las promociones general (80.4 % y 75.2 %) y de calidad (50.6 % y 53.1 %) en ambos años. El cumplimiento de las expectativas, satisfacción y calidad del proceso fue valorado de muy alto y alto (más 98 %) por los estudiantes en ambos cursos. Conclusiones: aunque existieron diferencias en el proceso enseñanza aprendizaje entre ambos planes, no hubo repercusión en la satisfacción de los estudiantes, calidad del proceso docente, ni los resultados académicos. La variante del plan "E" es más integral para la formación básica del apoyo vital.

Background: basic cardiopulmonary-cerebral resuscitation is present as its own course in the "D" and "E" study plans of the Medicine career; although in both the organization of the process has its particularities. Objective: to specify the differences in terms of structure, teaching process and academic results in the teaching of basic cardiopulmonary-cerebral resuscitation, between the "D" and "E" study plans of the Medicine career. Methods: a descriptive, prospective, cross-sectional study was carried out at Cienfuegos University of Medical Sciences from 2017 to 2019. Theoretical and empirical methods were used. To compare results, the student universe was used in both years, to evaluate satisfaction and quality a simple random sample. Descriptive statistical techniques were used. For both courses, a similar scenario and faculty were used. Results: the differences between both plans derive from the non-personal components of the teaching process; plan "D" has 20 hours and plan "E" 40, which expands its contents. All the topics and objectives of plan "D" were included in plan "E". There was similarity in the general (80.4% and 75.2%) and quality (50.6% and 53.1%) school grades in both years. The fulfillment of the expectations, satisfaction and quality of the process was valued as very high and high (more than 98%) by the students in both courses. Conclusions: although there were differences in the teaching-learning process between both plans, there was no impact on student satisfaction, quality of the teaching process, or academic results. The "E" plan variant is more comprehensive for basic life support training.

Cardiopulmonary resuscitation in the prone position: a systematic review of case series/reports / Reanimação cardiopulmonar em posição prona: uma revisão sistemática de séries/relatos de casos

Abstract Introduction The prone position is frequently adopted for surgical or critically ill patients in intensive care. Cardiorespiratory arrest in these patients may pose an operational challenge, in which delays resulting from mobilization to the supine position culminate in worse outcomes. Objective To provide clinical insight based on the synthesis of evidence from reports or case series on reverse cardiopulmonary resuscitation (reverse CPR) in surgical patients or invasive ventilatory support in severe acute respiratory distress syndrome. Methods This is a systematic review of reports or case series in PubMed, Scopus, Embase, and Google Scholar databases, in addition to a search of the gray literature. Case reports published in any language, reporting at least one case of prone cardiopulmonary resuscitation in patients of any age and in any care context, were considered eligible. Results Thirteen studies of fourteen cases of successful reverse resuscitation were retrieved. Three patients died within 30 days, while the others survived without complications or neurological sequelae. Conclusion Despite limited evidence to support clinical decision-making, prone resuscitation appears to be a feasible alternative in exceptional circumstances, where patient mobilization may result in additional harm, delay or interrupt advanced life support (compressions, high-quality early chest surgery, and defibrillation) or incur occupational risks to the health team.

Resumo Introdução A posição prona é um procedimento frequente de cuidados intensivos para pacientes cirúrgicos ou doentes graves. A ocorrência de parada cardiorrespiratória nestes pacientes pode representar um desafio operacional, no qual atrasos relacionados à mobilização para decúbito dorsal implicam em piores desfechos. Objetivo Oferecer um insight clínico a partir da síntese das evidências oriundas de relatos ou séries de casos sobre a utilização de reanimação cardiopulmonar reversa em pacientes cirúrgicos ou em suporte ventilatório invasivo na síndrome do desconforto respiratório agudo grave. Métodos Trata-se de uma revisão sistemática de relatos ou séries de casos condu-zida nas bases de dados PubMed, Scopus, Embase e Google Scholar, além de busca na literatura cinzenta. Foram considerados elegíveis relatos de caso publicados em qualquer idioma, que reportaram pelo menos um caso de reanimação cardiopulmonar em posição prona em pacientes de qualquer idade e em qualquer contexto de atendimento. Resultados Foram recuperados treze estudos que relataram quatorze casos de reanimação reversa bem-sucedidos. Três pacientes faleceram em um intervalo de 30 dias, enquanto os demais sobreviveram sem complicações ou sequelas neurológicas. Conclusão Apesar de evidências limitadas para suportar a tomada de decisão clínica, a reanimação em posição prona parece ser uma alternativa factível em circunstâncias excepcionais, nas quais a mobilização do paciente pode resultar em dano adicional, atrasar ou interromper o suporte avançado de vida (compressões torácicas precoces de alta qualidade e a desfibrilação) ou, ainda, incorrer em riscos ocupacionais à equipe de saúde.

The Role of Shunt Occlusion During Extracorporeal Life Support

ABSTRACT Introduction: The current recommendation for systemic to pulmonary artery shunt (SPS) patients requiring extracorporeal life support (ECLS) is to keep the shunt open, maintaining a higher pump flow. The practice in our center is to totally occlude the shunt while on ECLS, and we are presenting the outcome of this strategy. Methods: This is a retrospective analysis of patients who underwent SPS for cyanotic congenital heart disease with decreased pulmonary blood flow and required postoperative ECLS between January 2016 and December 2020. ECLS indication was excessive pulmonary blood flow, leading to either refractory low cardiac output syndrome (LCOS) or cardiac arrest. All patients had their shunts totally occluded soon after ECLS establishment. Results: Of the 27 SPS patients who needed postoperative ECLS (13 refractory LCOS, 14 extracorporeal cardiopulmonary resuscitation), wherein the strategy of occluding the shunt on ECLS initiation was followed, 16 (59.3 %) survived ECLS weaning and eight (29.6%) survived to discharge. Conclusion: Increased flow to maintain systemic circulation for a SPS patient while on ECLS is an accepted strategy, but it should not be applied universally. A large subset of SPS patients, who require ECLS either due to cardiac arrest or refractory LCOS due to excessive pulmonary flow, might benefit from complete occlusion of the shunt soon after commencement of ECLS, especially in cases with frank pulmonary edema or haemorrhage in the pre-ECLS period. A prospective randomized trial could be ethically justified for the subset of patients receiving ECLS for the indication of excessive pulmonary blood flow.
